Fig. 7. (a) Steady-state emission spectra of a 20 μM ZnPXZT1 solution upon the addition of 20 μM EDTA in 10 mM HEPES buffer (pH = 7) at room temperature in air. (b) Normalized steady-state and time-gated emission spectra of a 20 μM ZnPXZT1 solution upon the addition of 20 μM EDTA in air, λex = 330 nm, λem = 505 nm.
